All substances consist of particles.
Chemistry is a science that is taught in all schools as a rule from the seventh grade as a compulsory subject. It is the study of substances and particles, and their relationships to each other. Moreover, is mediated, which bonds the substances can enter into each other. There are many different types of particles, and this causes problems for some pupils difficulties. Do you want to be well prepared for your child in this regard questions, please obtain a simple explanation.
There are different types of particles in chemistry
- Give an account first that every conceivable material is composed of particles. Although the variety of materials is so high, only three kinds of particles can be distinguished: the atoms, molecules and ions. These terms should know an older schoolchild.
- A clear definition is mediated in chemistry class, this need not be provided. However, you can a few examples, so that your child can make the difference without a long and wide-ranging observations noted.
Enter for each particle simple examples
- Your child has safely ever had a metal in hand and maybe even rename some metals and different. Since metals are all atoms, this is good to remember. Expand the explanation so that there are also some non-metals, which are made of atoms, for example, sulfur or phosphorus.
- Ions have an electrical charge. If this is positive, says one cation, at a negative charge, the term anion is used. The substances are also referred to as ion substances.
- The most important molecules are oxygen, hydrogen, carbon dioxide and water. Since they differ markedly from metals, so your child has a fundamental knowledge that will make him to enter the chemistry easier.
If you bring materials with particle types in connection, you can easily notice in a further step the properties. Each substance has a particular characteristic, because it consists of precisely these particles.
